The 1992 Cubs were not a very good team. A 7-14 start put them in last place in the NL East May 1, and after winning Opening Day they didn’t get back over .500 until August 23, when they were 62-61.
Four weeks later, September 19, they were hosting the Cardinals for a doubleheader at Wrigley Field, made necessary by a June 17 rainout.
The Cubs won the first game 6-5. Between games — back in the day when single-admission doubleheaders were the norm — the crowd of 32,236 was asked to do something no Wrigley Field crowd had ever done before, nor has it happened since.
